HOLDER FOR TOQLS USED FOR TURNING AND PLANING IRON AND OTHER METALS..

Application filed May 13, 1926. Serial No. 108,946.

My invention is a fastening to secure tools either at an angle orstraight in the same holder.

The objects of my invention are, to provide a secure fastening, tofacilitate fastening and releasing tools, to avoid having a large,inconvenient front end, and to adapt the holder to hold tools either atan angle or straight.

My objects are attained by the devices described in the followingspecification and illustrated by the accompanying drawing. The partscomprising my tool-holder are A case, shown with all other partscomplete in Fig. 1.

A wedge with grooved shank bearing a left hand screw, as in Fig. 5.

C. A tightening-loosening screw with a. knurled knob, having a holeinside of it tapped left hand to receive the left hand screw on wedgeshank, and its outside threaded right hand to fit a tapped hole in therear end of the case, shown in Figs. 3 and 4.

D. A movable filler for changing angle of 'tool insertion, said fillerhaving a pin with projecting ends moving in a slot in the case, shown inFigs. 7 and 8. j

E. A screw or pin to enter groove in wedge shank, as shown in F ig. 1,and being 15 in Fig. 2.

Figure 1, in the drawing, is a side view ofthe holder, showing all partsand a tool place. j

screw in one piece with knurled Figs. 7 and 8 are two views of themovable er. The numbers for the parts are the same in all views. Thetightening-loosening screw that is in one piece with the knurled knob 13Fig. 4, is shown right hand, and the screw inside of it (in one piecewith the fastening wedge 11 Fig. 5) is shown left hand, but both screwsmay be of the same hand, if they have a different pitch.

Tools can be released also) by turning the fasteningloosening screw andits knurled knob 13 by hand. (Turning knob to 'right fastens tool and toleft loosens it on'diagram shown.) A pin' may be used in the holes 18Fig. 5, but it is seldom necessar The movable filler 12, Figs. 1, 2, 7and 8- can be placed adjoining the wedge 11 Fig.

tightened sufiiciently (and l and the tool inserted under it, being thenstraight with the holder instead of at an angle, as shown in thisdrawing. This alternative use of filler, enabling tool to be set eitherstraight or at-an angle, constitutes its neceslty'and is the mostimportant part of my invention. 4

The movable filler 12 Fig. 1, cannot be moved lengthways of tool-holderbecause the projecting ends of the pin: 14 Fi 7 are in the slot 16 inthe case 10 Fig. I, lit itcan be moved crossways of tool-holder, theprojecting ends of the pin 14 sliding in the slot, and the opening madeeither. straight or at an angle.

The end of pin 15 Fig; 2 rojects into groove 19 Figs. 5 and 6 in thefastening wedge 11 to prevent its turning around, if the knob 13 onfastening-loosenmg screw is turned while there is no tool in the holder.q

, for the tool 9 thus being The groove is made a little wider than thediameter of pin 15 to allow the fastening a case having a,-thr eadedhole'to grltlaceive a t g.
